-## Getting Started ##
+## Getting Started
 
 Create your GeoIP instance with appropriate access flag. `STANDARD` reads data from disk when needed, `MEMORY_CACHE` loads database into memory on instantiation and `MMAP_CACHE` loads database into memory using mmap.
 
-    import pygeoip
-    gi4 = pygeoip.GeoIP('/path/to/GeoIP.dat', pygeoip.MEMORY_CACHE)
-    gi6 = pygeoip.GeoIP('/path/to/GeoIPv6.dat', pygeoip.MEMORY_CACHE)
-
-### Country Lookup ###
-
-    >>> gi4.country_code_by_name('google.com')
-    'US'
-    >>> gi4.country_code_by_addr('64.233.161.99')
-    'US'
-    >>> gi4.country_name_by_addr('64.233.161.99')
-    'United States'
-    >>> gi6.country_code_by_name('google.com')
-    'IE'
-    >>> gi6.country_code_by_addr('2001:7fd::1')
